Christmas is coming and I am sure that more and more companies are taking the initiatives to stay ahead of their competition. Some are trying those cardboard displays while other is using the internet, and TV to stay ahead of the pack.
The most unique ads that I have seen so far are those companies who are using an airplane to advertise their products or service. I am sure that you will find it unique since this is not common. I am sure that those will see the air advertisement will surely take notice of the product easily since it is very different from the old fashion advertising.
